Description
SPresso which stands for Spatial Pressdown is a purely spatial script designed to achieve better compressibility without doing too much harm to the original detail.
SPresso was not designed for 1080p processing/encoding; due to its 3x3 kernel it works better on standard definition (SD) content like DVDs and possibly on 720p.
On noisy DVD/SD sources, compression gain usually is from 2% to 3% (light settings -> changes almost invisible) up to 10 to 12% (stronger settings -> slight, gentle softening, not very obvious).
Requirements
- AviSynth 2.5.8 or later
- Progressive input only
- Supported color formats: YV12
Required Plugins
- MaskTools2 2.0a48+
- RemoveGrain - part of the RemoveGrain v1.0b package.
Syntax and Parameters
- SPresso (clip clp, int "limit", int "bias", int "RGmode", int "limitC", int "biasC", int "RGmodeC")
- clip clp =
- Input clip.
- clip clp =
- int limit = 2
- Limit the maximum change for any given pixel.
- int limit = 2
- int bias = 25
- Something like "aggessivity": '20' is a very light setting, '33' is already quite strong.
- int bias = 25
- int RGmode = 4
- RemoveGrain mode for the luma (Y) channel. The default of "4" is the best in most cases.
- Mode 19 and 20 might work better in other cases; if set to 0, luma will be copied from the input clip.
- int RGmode = 4
- int limitC = 4
- Same as limit but for chroma.
- int limitC = 4
- int biasC = 50
- Same as bias but for chroma.
- int biasC = 50
- int RGmodeC = 0
- RemoveGrain mode for the chroma channels (UV) channels; by default the chroma is simply copied from the input clip.
- To process chroma, set RGmodeC=4 (or 19, 20, or any other compatible mode).
- int RGmodeC = 0
Examples
SPresso with all default values:
AviSource("Blah.avi") SPresso(limit=2, bias=25, RGmode=4, limitC=4, tlimiC=50, RGmodeC=0)
